History YMMV / KingdomHearts358DaysOver2

* FandomEnragingMisconception: If you value your like, '''DON’T''' call Xion a MarySue. It was ''sort of'' accepted back when she was revealed since there wasn’t much info about her beyond her basic description, but nowadays, especially with how much of a fan-favorite she is, you will be called out as an ignorant hater who doesn’t even ''know'' what a MarySue is.

** During Day 14, Roxas can talk with Larxene and she says “What are you looking at? ...Oh, dream on. It’s not gonna happen, pipsqueak.” Was Roxas actually attracted to Larxene to some extent despite how she mistreated him? Since she was the first woman Roxas really knew prior to Xion, it’s possible that, since Larxene is "very" easy on the eyes, Roxas could’ve had a small crush on her that just didn’t last long.

* AlasPoorScrappy: [[spoiler:Xion might not be a popular character but her death definitely made a lot of players cry]].

** Saïx and Lexaeus are incredibly good for soloing Mission Mode in spite of the buffed enemy stats. Saïx's high Crit rate and Crit bonus means he'll average a CriticalHit every three attacks, with each hitting dealing a large amount of damage (especially combo finishers). Combined with his lack of real weaknesses besides below-average Magic (which he doesn't really need), he makes soloing Mission Mode a breeze. Lexaeus, meanwhile, has the highest HP, Attack, and Defense, so he'll deal high damage consistently and can easily take hits.

* OneTrueThreesome: Axel/Roxas, Roxas/Xion, and Axel/Xion are all perfectly valid ships with plenty of subtext to draw evidence from. This is particularly true when you consider that in one Xion's secret reports she outright says that she loves Roxas and Axel, and the in the manga the three of them actually collectively conclude that running away from the organization and living together wouldn't be such a bad idea. Inevitably, some fans simply go this route.

** Many think this is the case for the story as a whole. People will agree this is one of the best, if not THE best, stories of the saga but it was completely dragged down (read: ruined) because A) A game filled with plenty of faults whether be bad controllers, tedious gameplay, or recycled concepts and worlds. B) An engine completely not up to the task of showing all the range of emotions all characters needed for such a tragic an emotional story (and this is about the HD version, let's not even begin with the DS engine). And C) A lackluster HD movie that feels more like a compilation of cutscenes than a well structured story (and this is not even talking about the battle scenes fiasco). For all these reasons, it's not unusual to find people who see both the novel and the manga as the definitive versions of Days.

** Riku and Mickey's adventures during the year between ''VideoGame/KingdomHeartsChainOfMemories'' and ''VideoGame/KingdomHeartsII'' are barely touched upon, bar Riku showing up occasionally. Knowing how they spent that time could have given them some extra development. What’s worse is that in the Kingdom Hearts II Ultimatium this was listed as one of the “unseen journies” alongside Roxas’s time with the Organization and Xehanort’s past, suggesting at one point there would be a game about this before it was merged with Days.

* SeinfeldIsUnfunny: This game is heavily criticized for having a [[ScrappyMechanic mission-based structure]] and [[ItsTheSameNowItSucks sharing many gameplay elements with]] ''VideoGame/KingdomHeartsII''...but considering this was originally made for the Nintendo DS, a portable system, those two aspects of the game worked in its favor upon its initial release. Nowadays, when most will be playing on emulators or systems that aren't portable, the game comes off as repetitive in comparison.

** Magic is extremely powerful even with the VancianMagic restrictions. Many enemies have elemental weaknesses and take huge amounts of damage from the correct spells, which can lead to normal {{mooks}} getting one-shot and stronger enemies losing multiple bars of health from a single cast. The Blizzard and Aero families get special mention for their associated StatusEffects, which both inflict a DamageIncreasingDebuff that can be consistently triggered with the basic or mid-tier versions.

* TierInducedScrappy:
** [[MasterofNone Xigbar]] in Mission Mode. His damage output is pathetic, his range isn't that much of an asset because it doesn't extend very far, and the ammo system only gimps him further by forcing him to occasionally reload before he can attack again. And even if you can adjust to all that, you still have to deal with his AwesomeButImpractical combos/shots that often [[EpicFail miss entirely]].
** [[SquishyWizard Donald]] has an impressive Magic stat that surpasses that of every other character, but he's a [[CripplingOverspecialization hard magic specialist and is otherwise the most inept fighter in the game]] with his small pool of weapons failing to compensate for incredibly weak and generally sluggish, close-range attacks as well as the worst Defensive stats in the game. His Magic stat lets him shine with shorter missions and/or enemies with elemental weaknesses, but you're often better off using another character with decent magic and a better selection of weapons to provide better attacks and/or better stats.

* HarsherInHindsight: Saix's actions in this game take on a whole new meaning when VideoGame/KingdomHeartsIII revealed that [[spoiler: Lea and Isa initially joined the Organization to find and rescue a girl that Ansem and Xehanort were experimenting on. And that while neither lost sight of the goal, Saix took Axel befriending Roxas and Xion as Axel abandoning their plan. It gets even worse when you consider the possibility that Saix saw Xion as Subject X furthering the resentment and sense of abandonment.]]

** [[spoiler:Roxas vs Saix.]]

** Saïx and Lexaeus in Mission Mode. Saïx's high Crit rate and Crit bonus means he'll average a CriticalHit every three attacks, with each hitting dealing a large amount of damage (especially combo finishers). Combined with his lack of real weaknesses besides below-average Magic (which he doesn't really need), he makes soloing Mission Mode a breeze. Lexaeus, meanwhile, has the highest HP, Attack, and Defense, so he'll deal high damage consistently and can easily take hits.

** Roxas's hatedom severely died down after the game's release with him being far more accepted thanks to game being upfront about his playable status and delving more into his character personal struggles than even the ''Final Mix'' edition of Kingdom Hearts II did. To the point where he now Rivals Sora in terms of popularity.
